Getting members from traffic

[brian]

First of all I must say that getting ranked for forum urls are not so easy but you have got a breakthrough so that's good. Try to build more and more content specially the discussions types which creates incentive to join and post.

Yeah, I completely agree with 'batman'. If you are getting traffic then you have successfully completed your first step.
Give away any kind of free offer or free ebooks for sign ups, it will definitely increase your joining rate. Create as much as fresh content per day. Not only interesting topics for discussion but also tutorials and how to's they will increase your trustworthiness in the community and people will join your forum.
